Not only did they have a lovely lady to show off the 16-layer BD, the company also released come interesting specifications.

Player compatible

Firstly, you will be glad to hear that the 400GB disc WILL be compatible with existing players, so when it does eventually hit shelves, your current machine of choice will be able to spin it.

Currently, there is only a read-only version available which will retail sometime between now and 2010. For those waiting to put all their movies on to one disc, then you'll have to wait until around 2012 for a rewriteable version.

As for the 1TB version, it apparently won't see the light of day until 2013.
